SHIMANO RT-CL900 Lock Interno With Magnet brake disc

With a focus on decreasing disc brake rotor heat deformation, the result of the new disc brake rotor is quieter than ever brake performance without sacrificing weight or heat dissipation. Features: - Quieter than ever, but with superb, consistent braking performance on any long, steep descents thanks to excellent heat dissipation - The new arm shape is more robust, leading to quieter operation - Heat dissipation paint boosts performance Specifications: - Average weight: 114 (160 mm) 96 (140 mm) - Ice Technologies: Yes - Ice Technologies Freeza: Yes - Center Lock: Yes - Outside Diameter_140 Mm: Yes - Outside Diameter_160 Mm: Yes - Ice Technologies Freeza W/ Heat Dissipation Paint: Yes - Pad Lining Shape Compatibility_Narrow: Yes Technology: Ice Technologies Freeza: - Ice Technologies Combined With Freeza Disc Brake Rotor Construction Rapidly Dissipates Heat For More Consistent Braking Performance In Extreme Conditions, Longer Pad Life, And Less Brake Fade And Noise. Benefits: - Lightweight clad rotors with heat dissipating paint on exposed aluminum layer segments provide superior cooling, consistent brake performance, and lighter operation under all conditions. - Clad brake rotors with Aluminum/Stainless fins support rapid heat dissipation which helps reduce maintenance, provide longer pad life, and create less brake fade and noise. Center Lock: - The Center Lock System Makes An Easy Rotor Installation Possible With Spline Mount And A Lock Ring. The Lock Ring Mounting System Reduces The Total Working Hours By Shortening The Amount Of Time Of Both Installation And De-Installation. In Addition, The Secure Fixing By The Spline Mount Enhances Precision And Rigidity While Improving Braking Efficiency.
